Household and similar electrical appliances - Safety - Part 2-34: Particular requirements for motor-compressors
IEC 60335-2-34:2012 deals with the safety of sealed (hermetic and semi-hermetic type) motor-compressors, their protection and control systems, if any, which are intended for use in equipment for household and similar purposes and which conform with the standards applicable to such equipment. It applies to motor-compressors tested separately, under the most severe conditions that may be expected to occur in normal use, their rated voltage being not more than 250 V for single-phase motor-compressors and 480 V for other motor-compressors. Examples of equipment which contain motor-compressors are:
- refrigerators, food freezers and ice makers (IEC 60335-2-24);
- air-conditioners, electric heat pumps and dehumidifiers (IEC 60335-2-40);
- commercial dispensing appliances and vending machines (IEC 60335-2-75);
- factory-built assemblies for transferring heat in applications for refrigerating, air-conditioning or heating purposes or a combination of such purposes.
This standard does not supersede the requirements of standards relevant to the particular appliance in which the motor-compressor is used. However, if the motor-compressor type used complies with this standard, the tests for the motor-compressor specified in the particular appliance standard may not need to be made in the particular appliance or assembly. If the motor-compressor control system is associated with the particular appliance control system, additional tests may be necessary on the final appliance. Keywords: Motor compressor, hermetic; semi-hermetic
This publication is to be read in conjunction with IEC 60335-1:2010.
Appareils électrodomestiques et analogues - Sécurité - Partie 2-34: Exigences particulières pour les motocompresseurs
La CEI 60335-2-34:2012 traite de la sécurité des motocompresseurs étanches (de type hermétique et hermétique accessible) et, le cas échéant, de leurs systèmes de protection et de commande, qui sont destinés à être utilisés sur les appareils électrodomestiques et analogues et qui sont conformes aux normes applicables à de tels matériels. Elle s'applique aux motocompresseurs soumis à essai séparément, dans les conditions les plus sévères qui peuvent se produire en usage normal, la tension assignée n'étant pas supérieure à 250 V pour les motocompresseurs monophasés et à 480 V pour les autres motocompresseurs. Comme exemples d'appareils équipés de motocompresseurs, on peut citer:
- les réfrigérateurs, congélateurs et fabriques de glace (CEI 60335-2-24);
- les climatiseurs, pompes à chaleur électriques et déshumidificateurs (CEI 60335-2-40);
- les distributeurs commerciaux avec ou sans moyen de paiement (CEI 60335-2-75),
- les ensembles montés en usine pour le transfert de chaleur dans des applications de réfrigération, de climatisation ou de chauffage, ou toute combinaison de ces fonctions.
La présente norme ne remplace pas les exigences des normes applicables aux appareils dans lesquels des motocompresseurs sont utilisés. Toutefois, si le type de motocompresseur utilisé est conforme à la présente norme, il est possible que les essais pour les motocompresseurs spécifiés dans les normes relatives aux appareils particuliers n'aient pas besoin d'être effectués sur l'appareil ou l'ensemble particulier. Si le dispositif de commande du motocompresseur est associé au dispositif de commande de l'appareil particulier, des essais complémentaires peuvent être nécessaires sur l'appareil final. Mots clé: motocompresseur, hermétique, hermétique accessible
Cette publication doit être lue conjointement avec la CEI 60335-1:2010.

Part 2-34: Particular requirements for motor-compressors
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This consolidated version of the official IEC Standard and its amendment has been prepared
for user convenience.
IEC 60335-2-34 edition 5.1 contains the fifth edition (2012-05) [documents 61C/508/FDIS and
61C/517/RVD] and its amendment 1 (2015-05) [documents 61C/597/FDIS and 61C/603/RVD].
